Abstract
The utility model relates to an integral fire hydrant middle segment which comprises a main body of a cylindrical middle segment and a valve clack, wherein, the valve clack which is connected together with a valve rod is arranged on a water inlet at the lower part of the main body of the middle segment. The utility model is characterized in that two guiding studs are symmetrically arranged on the inner wall of the main body of the middle segment, wherein, a drain hole is horizontally arranged on one guiding stud. A sliding connecting piece which is connected with the valve rod is arranged on the upper surface of the valve clack. Slide grooves which are matched with the guiding studs are arranged on both sides of the sliding connecting piece. The length of each of the slide grooves is not bigger than the distance from the drain hole to the water inlet. The lower surface of the valve clack and the matched bottom surface of each of the slide grooves are equally coated by sealing adhesive layers. The utility model which enables the shapes of parts to be simple to through the improvement of the middle segment of a fire hydrant raise the reliability and the safety of the machining and the pressure test of a product. The positioning and the slide of the valve clack are organically unified with the arrangement of the drain hole so that each action has two functions. The lower surface of the valve clack and the matched bottom surface of each of the slide grooves are integrally sulfurized and encapsulated with good sealing effect and high anticorrosive capability.
Description
(1) technical field
The utility model relates to fire-fighting equipment, particularly a kind of important composition parts of fire hydrant---save in the monoblock type fire hydrant.
(2) background technology
At present, in the design and manufacture process of fire hydrant, the structure of joint and flap is varied in the fire hydrant, but all has a common defective, be delivery port with discharge opening because function different, all be that its seal form is set respectively on the structure, the result is the part shape complexity, is difficult for processing, check, the first-time qualification rate of assembling is lower, poor reliability, required part processing, buying be difficult for to be grasped, and are not easy to production management and reduce cost.
(3) technology contents
A kind of simple shape that the purpose of this utility model designs at existing problem in the above-mentioned prior art just, safe and reliable, make assembling easily, save in the low monoblock type fire hydrant of product cost.
The purpose of this utility model realizes by following scheme: in this monoblock type fire hydrant joint comprise abridged edition body in the cylindrical shape and be arranged in the flap that links together with valve rod on the abridged edition body lower water inlet, wherein: middle abridged edition body inwall is symmetrically arranged with two guiding studs, laterally offer a spilled water hole on a guiding stud therein, the flap upper surface is provided with the slip connecting piece that links to each other with valve rod, the chute that slip connecting piece both sides are provided with and the stud that leads is complementary all is coated with sealant layer at the lower surface of flap and the cooperation bottom surface of chute.
In the utility model, chute length≤spilled water hole lower edge can make (when pushing down delivery port) when flap comes downwards to sealing station that apart from the distance of water inlet end face the spilled water hole that is originally sealed up by chute exposes just, thereby plays two kinds of functions of an action.Described slip connecting piece center is the cylindrical structure that is used for the plug-in mounting valve rod.Valve rod also can take other usual manner to be connected with the slip connecting piece, connects as pin, rivet.
The utility model in use, promptly in fire hydrant assembling back (upper end of middle joint and the flange coupling of fire hydrant epimere, the lower end and the flange coupling of the water supply mouth of pipe of middle joint), when not needing to fetch water, by rotation valve rod, it is descending along the guiding stud to drive slip connecting piece and flap, until flap fluid sealant face water inlet is compressed, delivery port is closed, and the spilled water hole on the stud that leads this moment is opened, and residual water can be flowed out by spilled water hole in the key.When needs are fetched water, the counter-rotation valve rod, it is up along the guiding stud to drive slip connecting piece and flap, and the chute fluid sealant face on the slip connecting piece is sealed spilled water hole, and water inlet is opened, and current promptly enter fire hydrant, can fetch water.
The utility model is by the improvement to saving in the fire hydrant, make the parts shape more succinct, the processing of product, the reliability of pressure testing have been improved, the setting of the location of flap, slippage and spilled water hole is united, make each action all have two kinds of functions, promptly flap is closed delivery port downwards, opens spilled water hole, upwardly open delivery port, close spilled water hole.And at the lower surface of flap and the whole sulfuration in the cooperation bottom surface encapsulate of chute, good sealing effect, antiseptic power is strengthened.
The utility model since interior shape simplify, the stud of two double as guide seal covers, precision can be controlled in the 0.1mm, processing, detect, assembling easily, need not match, product cost reduces, and the reliability and the security that have improved fire hydrant.
